Can hand over water inlet, the water inlet end will be submerged, another person to the outlet to open the outlet end, both sides are ready to open both ends of pumping, the pumping process must remain in the water inlet end of the pond, otherwise have to repeat the process.

Hydraulic test verification pressure test: Test hose and assembly under verification pressure, continue 30s-60s, whether to produce leakage, deformation and damage. Compression deformation test: keep 1 minutes under the specified pressure (work pressure, verification pressure or other pressure below the proof pressure), measure the length and diameter of the hose, twist angle and bend. Bursting pressure test: Determination of the pressure at which the hose burst during the specified step-up rate. Leak test: save 5min at 70% of the minimum blast pressure, and check again and again for leaks or damage. Due to the fact that water is often used in tests, the pressure and leakage pressure at normal temperatures may be slightly lower at normal temperatures.

Q:Do the rubber joint and Y filter need flange connection?

Rubber hose joints are usually externally threaded, and type Y filters are internally threaded and are directly connected to the same caliber.Flange connection also has ah, according to demand

Q:Can high speed air flow through a rubber tube and produce static electricity?

It is not easy to describe the magnitude of the voltage generated by the static electricity of these aggregates, which is related to the humidity, velocity, characteristics of the rubber material, and the surrounding environment.

Q:The rubber is sheathed on the metal cylinder. How can it be connected?

With the combination of metal rubber is coated with adhesive before production and rubber vulcanization shaping, you can use this temporary experiment 502 geliahao for glue or adhesive, but the disadvantages of this thing with winter is not strong, the metal surface must be clean

Q:What are the types of hose connectors?

In general, we'll sort it out first.It is divided into A/, B/, C/, D/, F/, G/, H/, K/A/ flat sealing type,Type B/ is a jacketed joint that matches the 24 degree C type,C/ points 24.60. and 74 degrees, and in turn with 24 degrees g, type and 74 degree g match,D/ is a spherical sealed typeF/ is a disc type jointG/ divided into 3 kinds, namely 24, 60, and 74 degrees, and the same degree of C matching seal,The H/ machined a sealing groove in the cone of 24 degrees g,K/ a quick change connector, it goes nuts, adopts the sealing method, the piston type to facilitate the replacement of Yucca Shaw, commonly used in coal mine which is commonly used to.

Q:What's the metal hose for fire fighting?

1 the metal hose is made of 1Cr18Ni9Ti stainless steel, and has strong corrosion resistance.The 2. hose tube is made of thin wall stainless steel tube. It has strong flexibility, flexibility, strong bending and vibration resistance, and reinforced protection of woven mesh sleeve, so that it has higher bearing capacity.The connection of the ends of the 3. flexible pipes can be made into other connecting ways except the thread and the flange standard, so that the connection and the use are convenient.4. the product is not only suitable for mating with rotating joint, but also widely used in soft connection of many kinds of fluid medium transportation.

Q:What is the method of making large diameter rubber joint?

Rubber joint also known as shock absorber, shock absorber throat, the main function is to shock absorption, noise reduction, protection of the pipeline, compensation pipeline expansion, cold caused by displacement.Its structure: both ends are two carbon steel flanges, the middle is rubber shock absorption part.

Q:The difference between hose and rubber tube

Silicone tube: also known as silicone tube. Used as liquid, gas, and other materials to circulate and coat carriers.Latex tube: latex tube is made of latex material of different thickness of tubes, mainly used in hospitals, equipment factories, power plants, research laboratories and other fields, but also related to bungee jumping, trampoline and other places of entertainment.

Q:How can the tightness of rubber tube and metal pipe joint be ensured?

See how much your pipe diameter, diameter is around 10%, the metal pipe is inserted into the 2-3 rubber tube diameters, almost, don't worry, coupled with a hose clamp.
